Why were Triassic animals so weird?
The Triassic was full of creatures that look a lot like other, more modern species, even though they’re not closely related at all. The reason for this has to do with how evolution works and with the timing of the Triassic itself: when life was trapped between two mass extinctions.
What’s the biggest dinosaur that ever lived?
Patagotitan mayorum

Why did sharks survive when dinosaurs didn t?
Having a skeleton made of lightweight cartilage allows sharks to conserve energy and swim long distances. Because shark skeletons are made of soft cartilage, which doesn’t fossilize well, most of what scientists know about ancient sharks comes from teeth, scales and fin spine fossils.
